Abstract

Electric vehicle dynamic wireless power charging technology is to lay the transmitting coil below the ground. When the electric vehicle with receiving coil is running on this road, the power grid is continuously transmitted to the driving motor of electric vehicle through transmitting and receiving coil, thus realizing the dynamic wireless charging of electric vehicle. In recent years, the dynamic wireless charging technology of electric vehicles has attracted more and more attention of research institutes because of its long endurance mileage, small carrying capacity of on-board batteries and flexible charging methods. In this paper, direct field-circuit coupling multi-physical field simulation is carried out to study the influence of parameters on the dynamic coupling process of the dynamic wireless charging system of electric vehicle. Through simulation analysis, the effect of different parameter changes on the system is effectively reflected. And the real working characteristics of the system are estimated.
